Cuba in the Dark: Failure at the Guiteras Plant
Cuba’s energy crisis reached a new critical point this March 5, 2026. A major failure at the Antonio Guiteras Thermoelectric Power Plant (CTE), the country’s main generating facility, has left more than two-thirds of the national territory without electricity, including much of Havana.
A Power Grid on the Brink of Collapse
The electricity generation deficit on the island has exceeded 2,000 megawatts (MW), an alarming figure that reflects the precariousness of Cuba’s energy infrastructure. The shutdown of the Guiteras plant, located in Matanzas, triggered a domino effect that disconnected vital circuits from Camagüey to Pinar del Río.
Authorities from the Ministry of Energy and Mines have described the situation as “extremely complex,” noting that a lack of fuel—specifically diesel and fuel oil—exacerbates the inability of smaller plants to meet demand.
Impact on Daily Life
For Cubans, this new massive blackout is not an isolated incident but the latest chapter in an endless crisis. On the streets of the capital, businesses have been forced to close, and basic services have been interrupted.
“We don’t know what to do anymore. Without power, there’s no water, and food spoils in the refrigerators,” says a resident of Central Havana. The situation is even more tense in the central and eastern provinces, where power cuts exceed 18 hours a day.
Frequently Asked Questions About Cuba’s Energy Crisis
Why is the Antonio Guiteras power plant so important? It is the most efficient plant in the country and its strategic location in the west helps stabilize the National Electric System. Its shutdown almost always guarantees massive blackouts.
How long will it take to restore service? There is no exact date. Repairs on such old plants are always uncertain and depend on the availability of spare parts and specialized personnel.
Is it just technical failures or a lack of oil? It’s a combination of both. Cuban plants have exceeded their lifespan and haven’t received proper maintenance, while a foreign currency crisis prevents stable fuel purchases.
What measures has the government taken? Non-essential economic activities have been halted, and scheduled power cuts have increased, though the current deficit makes scheduling almost impossible to follow.
Crisis Context in 2026
This event occurs amidst high inflation and shortages of basic goods. The transportation crisis and problems with basic food supplies keep the population in a state of constant vulnerability.
